Rendering the same 6-paragraph, 65-line source markup file (reStructuredText or pandoc's Markdown flavor) into a 154-line HTML 5 target file:
py36-rst2html5: 1.05 seconds
py36-docutils: 0.65 seconds
hs-pandoc: 2.50 seconds
Rendering the same source file content through Jamal, "Just Another Macro Language," a perl script from 1997 & last updated 2010:
jamal: 0.05 seconds
These look tiny now, but what happens when I go over 100 pages then tweak the template?
